## Capabilities

- Creates new PPTX decks from HTML slides with precise positioning.
- Edits existing PPTX files by unpacking and modifying OOXML content.
- Uses template inventories to map content into existing slide layouts.
- Generates thumbnail grids for visual review and layout validation.
- Validates Office XML structure before repacking edited presentations.
- Replaces text while preserving paragraph, bullet, color, and font properties.

## Use Cases

- Build Executive Slide Decks: Create polished decks from briefs, data summaries, and approved visual direction.
- Update Branded Templates: Reuse existing template slides while replacing text and preserving layout rules.
- Repair Presentation Structure: Inspect OOXML, validate relationships, and repack presentations after targeted edits.

## Prompt Templates

### Create a Basic Deck

```
Create a 6-slide PowerPoint about [topic]. Use clear titles, concise bullets, and a professional visual style.
```

### Apply a Template

```
Use [template.pptx] to create a deck from this outline: [outline]. Match each section to suitable template slides.
```

### Edit Existing Slides

```
Update [deck.pptx] with these changes: [changes]. Preserve the existing design and validate the result.
```

### Diagnose OOXML Issues

```
Inspect [deck.pptx] for broken relationships, invalid XML, and layout problems. Fix issues and explain the changes.
```

## Limitations

- Requires local presentation tools and libraries to be installed.
- Cannot guarantee perfect rendering across every PowerPoint version.
- Complex animations and custom macros may need manual review.
- Works on local files and does not provide cloud presentation hosting.

## Best Practices

- Use thumbnail grids after each major edit to catch layout and readability problems.
- Validate OOXML immediately after structural changes and before repacking the final file.
- Match template layouts to actual content count before replacing placeholder text.

## Anti Patterns

- Do not force content into a template layout with too many placeholders.
- Do not edit raw XML without validating relationships and schema rules afterward.
- Do not rely only on text extraction when comments, notes, layout, or media matter.

## Security Audit

- Audited at: 2026-07-21T08:00:56.529\+00:00
- Summary: The audit confirmed four unsafe ZIP extraction calls that process Office archives without member-path validation. It also confirmed two documented, user-mediated sudo installation commands; most remaining static findings are syntax, schema, documentation, or expected local document-processing false positives. Static review was capped at 400/506 representative findings; omitted static matches are unconfirmed, so automatic publishing stays disabled until manual review.
